1. Which type of heat transfer, caused by uneven heating, moves air and water
1 answer:
Answer:
Convection
Explanation:
Convection is the transport of heat by a fluid like air or water.
Hot air is less dense than cold air, so hot air rises and cold air sinks.
In weather, convection refers to the vertical transfer of heat and moisture from the surface to a cooler area aloft.
Conduction is wrong. It involves the movement of heat by collision of molecules.
Radiation is wrong. It does not need a medium to transfer the heat.

Empirical formula of ionic compound formed by two ions and
is
(for
) of AB (for x = y)
The above empirical formula is in accordance with charge neutrality principle
Here each cation ( and
) can form two ionic compounds by combining with two given anions (
and
).
So the four ionic compounds are:
